Radeon Instinct


Radeon Instinct is AMD's brand of deep learning oriented GPUs. It replaced AMD's FirePro S brand in 2016. Compared to the Radeon brand of mainstream consumer/gamer products, the Radeon Instinct branded products are intended to accelerate deep learning, artificial neural network, and high-performance computing/GPGPU applications.
The Radeon Instinct product line directly competes with Nvidia's Tesla and Intel Xeon Phi lines of deep learning and GPGPU cards.

Products

The three initial Radeon Instinct products were announced in December 2016, with each based on a different architecture.

MI6

The MI6 is a passively cooled, Polaris 10 based card with 16 GB of GDDR5 memory and with a <150 W TDP. At 5.7 TFLOPS, the MI6 is expected to be used primarily for inference, rather than neural network training. The MI6 has a peak double precision compute performance of 358 GFLOPS.

MI8

The MI8 is a Fiji based card, analogous to the R9 Nano, and expected to have a <175W TDP. The MI8 has 4 GB of High Bandwidth Memory. At 8.2 TFLOPS, the MI8 is marked toward inference. The MI8 has a peak double precision compute performance 512 GFLOPS.

MI25

The MI25 is a Vega based card, utilizing HBM2 memory. The MI25 performance is expected to be 12.3 TFLOPS using FP32 numbers. In contrast to the MI6 and MI8, the MI25 is able to increase performance when using lower precision numbers, and accordingly is expected to reach 24.6 TFLOPS when using FP16 numbers. The MI25 is rated at <300W TDP with passive cooling. The MI25 also provides 768 GFLOPS peak double precision at 1/16th rate.

Software

MxGPU

The MI6, MI8, and MI25 products all support AMD's MxGPU virtualization technology, enabling sharing of GPU resources across multiple users.

MIOpen

MIOpen is AMD's deep learning library to enable GPU acceleration of deep learning. Much of this extends the GPUOpen's Boltzmann Initiative software. This is intended to compete with the deep learning portions of Nvidia's CUDA library. It supports the deep learning frameworks: Theano, Caffe, TensorFlow, MXNet, The Microsoft Cognitive Toolkit, Torch, and Chainer. Programming is supported in OpenCL and Python, in addition to supporting the compilation of CUDA through AMD's Heterogeneous-compute Interface for Portability and Heterogeneous Compute Compiler.
